.SH DESCRIPTION
|
|
.I Zhm
|
|
is the link between a client machine and the zephyr server. All
|
|
notices sent from programs on the client are funneled through
|
|
.I zhm.
|
|
This allows all client programs to be much simpler in function, since
|
|
the HostManager is responsible for handling errors, retransmitting
|
|
lost notices, and holding all notices until they are acknowledged.
|
|
.PP
|
|
The
|
|
.I -d
|
|
option turns on debugging mode, and sends its information to syslog
|
|
LOG_DAEMON messages.
|
|
.PP
|
|
The
|
|
.I -n
|
|
option causes zhm to not attempt to put itself in the background.
|
|
.PP
|
|
The
|
|
.I -h
|
|
option causes
|
|
.I zhm
|
|
to send a shutdown message and exit upon delivery of a SIGHUP signal.
|
|
The normal action on SIGHUP is to send a flush notice to the zephyr server.
|
|
.PP
|
|
The
|
|
.I -r
|
|
option causes
|
|
.I zhm
|
|
to send a boot notice to the server and exit when the notice is acknowledged.
|
|
.PP
|
|
The
|
|
.I -i
|
|
option indicates that
|
|
.I zhm
|
|
is being started by
|
|
.I inetd(8).
|
|
When this option is specified,
|
|
.I zhm
|
|
assumes that file descriptor zero (0) is bound to the UDP datagram port
|
|
designated for hostmanager use. In this mode, SIGHUP is handled as if the
|
|
.I -h
|
|
option were specified.
|
|
.PP
|
|
The
|
|
.I -f
|
|
option disables the "flush" operation which allows any client to flush
|
|
all subscriptions for the host.
|
|
.PP
|
|
The
|
|
.I -N
|
|
option supresses the initial "boot" message that flushes all subscriptions
|
|
for the host, which is useful if you're restarting zhm on a host that
|
|
people are using.
|
|
.PP
|
|
The optional
|
|
.I server
|
|
arguments are used to replace the set of server names supplied by
|
|
the
|
|
.I hesiod(3)
|
|
name server.
